Application filed November 12, 1912. Serial No, 730,862.

To all wlw/m. it may conce-fm Be it known that l, Unmut A. lininnl'nn]- a citizen of thenited States, und resident ot' Short Hills, in the county of Essex and State of New Jersey, have in#l rented certain neur and useful improvenients in Processes of Treating Match- Splints, of which the following;` is a specification.

This invention relates to an improvement in the process of treating' Inntch splints set out in Letters Potent of the United States 12, 1912, which process us therein described consists in subjecting;V the splints to a hath comprising un unctuous inflammable substance in which is maintained in suspension a inely divided material that is adapted to impro@ nnte lthe splints and render them non-gimp ingr when the splints, :is finished matches, nre ignited and the flame extinguished. By way of illustration the specific infin-minable substance mentioned is melted paraffin (pr-ollin Wax) and the specic impregnnling material is boracic acid.

The present invention has for its object to provide u simple and ctlicient process hereby the infianirnable and non-glowing properties shall be imparted to the match splints. To that end prepare a liquid hath of unctuous inznnmnble substance car* rying an inorganic material reduced preternbly to such n degree ot inenessthntit will` tend to be und remain in suspension in the This material is ot' n character to impart the requisite non-glowing properties to match splints impregnated therewith. The muss is agitated in order thoroughly to conuningle the ingredients thereof. und in thu-t condition it is caused to tion' in a uniform strcoin, Without sur- 'ieee agitation., through the dinping path. rthe spiints are dipped to si 'ont depth and for o sniiicient period of K into the flowing :nnss until 'the requisite impregnation of splints with the components of the 'mixture has been eiected.

i prefer to employ pnrs'iiin wax the iniianirnable material and hor* f :ic/id the material hy which the non-gimyn 1g property is imparted to the 'r although, of coursej in pursuance of my invention other met of e character to impart 'the iniiamnieole and nen-H properties to the splints, they enipicytd type wherein the splints are inserted row An eilicient mode oi' procedure is as follows: The pnrniiin Wax iu a melted state is introduced into n suitable tank and the finely-divided borne-ic :reid is added to the liqnelied substance in the proportion, by Weight, of paratui one hundred ports und boracic acid seven parts. These ingredients and progiiortion are given merely by Way of example, as they admit of Wide variation without departure from my invention. The tank is provided with suitable stirringr devices whereby the materials may he Well agitated and the acid thus be thoroughly coininingled with the paraffin. From this trink the fluid mixture, either by means of n pump or grzuf'itation, is delivered to and 'caused to tion', in the presence of heat, in a uniform stream through a dipping trough in a manner to insure a continuous circulation of the mixture through the tank and trough.

Vv'hcn my invention is used in connection With the manufacture of matches upon a continuous match making machine of the by row in an endless carrier and thereby held in spaced relation to each other 'and transported through the match making path, the dipping trough is suitably iocayted beneath the route of the carrier, so that the depending splints on the latter during; their travel toward the head-composition applyine devices can be dipped into and subjected tothe action of the flowing mass until the efiicient impregnation of the splints with the respective components of the stream shall have been attained.

The annexed drawing illustrates an apparat-us ot' simple and eiiicient construction and operation for practically carrying out my ilwention, Figure i. being pien View of the apparatus, showing s portion of the endless splint carrier, and Fig. 2 s, transverse vertical section, ss en the line 9?2 of Fig. i. Y

i. designates a steam-iaijzheted mixing tenir withi which is mounted to rotate shaft equipped wit i mining und propelling' blades This shnfuis driven from e suitable l.. source ot' power.

et de joutes carrier 6 of the during the progoi splints there- 11 in extend down into the trough. The l trough is in communication at its respective ends with the adjacent ends of the mixing tank, by means of steam-jacketed conduits 7, 8 respectively. The conduit 7 is provided' with a `reared pump 9,' by means of whichl circulation of the fluid mixture through the tank and trough is maintained, and the conduit 8 is provided with a suitable regulating valve 10.

It is to be understood that the form of apparatus just described is herein given by way of example only.

I claim l. The process of treating match splints to impart inflammable and non-glowing properties thereto, which consists in ip ping the splints into a streamof unctuous inflammable liquid carrying an antiglowi{ig material.

2. The process of treating match splints to impart v inflammable and non-glowing properties thereto, which consists in dipping,- the splints into a stream of an inflammable liquid'carrying a finely-divided and anti-glowing' material.

3. The process of treating match splints to impart inflammable and non-glowing properties thereto, which consists in dipping the splints into a stream of an unctuous inflammable substance carrying a finelydivided anti-glowing materlal.

Copies of this patent-.allay be obtained for ve cents each, by addressing the Commissioner of Patents.

4. The process of treating match splints to impart inflammable and `l10n-glowing; properties thereto, which consists in mixing with an unctuous inflammable substance a inely-dii/ided material which will render the splints non-glowing when they` have been ignited and the flame extinguished, causing' a continous flow of'said mixture through a dipping bath, and dipping the lsplints into the flowing mixture.

5. The process of treating match splints 'to impart inammable and non-glowing properties thereto, which consists in providing a mixture of melted parailin Wax and an ant'i-,eflowingr material, causing the mixture to flow in a stream, and dipping the splints into the flowing mixture.

6. The processof `treating match splints to impart inflammable and non-glowing properties thereto, which consists in melting paraffin wax, adding thereto a finely-divided anti-glowing material, agitating the. mixture, causing it to How in a stream 1n the presence of heat, and dipping4 the splints into the flowing mixture.
